Aurora Australis

Aurora australis (also known as the southern lights, and southern polar lights) is the southern hemisphere counterpart to the aurora borealis. In the sky, an aurora australis takes the shape of a curtain of light, or a sheet, or a diffuse glow; it most often is green, sometimes red, and occasionally other colors too. But be aware. Sightings are fleeting and faint. And these images are often faint to the naked eye.
Where to see an Aurora: 
Find a spot where you have a clear view of the horizon when looking South.
Ideally pick a spot away from any light pollution where possible.
